Excelente guia todo muy bien detallado.
Hi, My mac, I bought in late 2011 (december), doesn't work on internal harddrive( I replaced it to SSD, year agao), but when i use SATA cable externally, it works perfect. I get the circle and slash sign when I try to boot with internal drive cable, but SATA works fine. Do I need to replace my internal cable?
that probably means the cable is done. Just replace it and find out. It worked out that way for myself. If its not the cable, well it was going to cost more to bring in to a repair shop anyway.
Having almost got to the stage when i was going buy a new macbook - I found this, and decided to give it a go, having had the death folder and my computer not responding to any of the so -called fixes and recoveries. Hey presto after 30 minutes of being an IT engineer, thanks to be the above guide, I am now up and running and not having to buy a new one - good saving and more confidence of how to fix my mac thanks to the clear directions and pics - superb

Thanks very much for this precise and well described guide. Looked like my son’s MacBook HDD was dead until I found a lot of talk on the forum about the hard drive cable being a common fault. Took the chance of replacing the cable first and could not have done so without this guide. Pleased to say the hard drive was actually fine and having successfully replaced the cable he’s now up and running again. Thanks
